Set the maximum data-transfer rate
Use the following command:
SET THIS_CONTROLLER PORT_1_TRANSFER_RATE_REQUESTED = speed
or
SET THIS_CONTROLLER PORT_2_TRANSFER_RATE_REQUESTED = speed
If you are configuring dual-redundant controllers, also set the transfer rate for the
other controller. However, if you are running more than one HSZ80 SCSI host port on
the same bus, you must set their transfer rates to be identical. Use the following
command:
SET OTHER CONTROLLER PORT_1_TRANSFER_RATE_REQUESTED=speed
or
SET OTHER CONTROLLER PORT_2_TRANSFER_RATE_REQUESTED=speed
See Chapter 5, "CLI Commands," for more information about setting the data transfer
rate.
